ATTORN EYS Tlite tates 3,062,368 CLOTH REEL Richard G. Dunn, Barrington,RJ., assignor to The Real- Reel Corporation, a corporation of RhodeIsland Fried Apr. 22, 1960, ser. No. 24,154 3 Claims. (Cl. 20G- 50) Thisinvention relates to a reel for the winding thereon of some web materialsuch as a textile fabric.

Heretofore, in the manufacture of reels or cores upon which web materialhas been reeled or wrapped, it has been the practice to form these coresin various manners with a view in mind to provide a fiat end surfaceupon which printed matter may be displayed. The appearance of thepackage depends largely upon the end of the reel upon which this printedmatter is displayed.

In an attempt to reduce the expense of the above type reel, variousforms of reels have been made. Reels originally were formed by woodenframework covered with paper with end caps backed up by a solid woodenstrip, the end caps being printed with the desired printed matter. Thiswooden backup provided a very strong and desirable reel and a goodappearing end. However the construction of such a framed reel was ratherhigh in cost. In order to reduce the expense and provide a reel of thisgeneral type instead of using a wooden framework, a piece of corrugatedboard was doubled upon itself to form the body part of the reel and acardboard at strip was provided at the end which had a cardboard endwall and side walls extending along the end portions of the reel but noedge walls and this cardboard end supported a paper which bridged theside walls and provided the edge surface while covering the end and sidewalls and upon which the printed matter was displayed. In order tofurther reduce construction costs, a type of end cap for the corrugatedboard body was formed by folding cardboard upon itself into a shapehaving single thickness end, side and edge walls with the end cap formedof a white surface and the printed matter printed directly upon thissurface. However, it was found that in all of these reels the cornerswould crush due to excessive pressure which destroyed the liat desiredappearance of the end of the reel where the printed matter occurred. Thestrength could not be well obtained with a U-shaped end cap such as wasused. Further attempts to reduce expense consisted in providing a singlethickness of rather heavy chipboard with end caps which were let intothe end of the board with a printed covering material or with a U- shapesupporting end over which a printed U-shape piece extended. However,this construction likewise lacked the edge wall support and did not havethe desired rigidity in the corners and further it was not suiiicientlythick in between the ends so as to provide a smooth reel. The cost wasnot appreciably reduced from that just before mentioned.

In all of these constructions, the weakness was at the corner spots ofthe core where there was either no good supporting thickness of materialor such support was of a single ply of material and insufficient.

An object of this invention is to provide a stronger support at thecorners of the reel through the utilization of a reinforced corner onthe cap which is placed on the end of the reel.

Another object of this invention is to provide this reinforcement byfolding a sheet of stock so that the increased thickness may be had bymultiple plies of the stock at the point desired.

A further object of this invention is to so provide the end cap that theusual operations of assembling the end cap on the end of the reel willbe substantially those which have previously been performed by placingend caps on a reel of the ordinary construction.

Another object of the invention is to provide an end cap of cardboardwhich will be scored so that it will readily bend into the shape desiredeasily by the manipulation of the operator.

A further object of the invention is to provide an end cap upon Whchprinting will occur and which printing may be had at the same time thatthe scoring takes place so that in mechanical manufacture one loperationof scoring and printing may be accomplished at the same time.

With these and other objects in View, the invention consists of certainnovel features of construction as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

FIG. l is a perspective View of the cloth reel of this invention;

FIG. 2 is a section on line 2,-2 of FIG. 1;

FIG. 3 is a perspective View of the end cap with one end folded and theother end unfolded; and

FIG. 4 is a plan view of the blanked-out end cap before folding.

In proceeding with this invention, I utilize the body of the reelsubstantially of the construction which has heretofore been provided andform an end cap for the reel which will be reinforced to a greaterextent than end caps heretofore used. I accomplish this increasedreinforcement by providing three plies of stock, one folded from the endand one folded from each of two side walls extending from the end Wallso that three plies of stock are provided at the corner locations wheremost usual collapsing of the reel occurs.

With reference to the drawings 1t) designates the body of the reel whichis formed by utilizing a core of corrugated board, there being a facestrip 11 and a wavy form of corrugation 12 with a capping sheet 13 ofpaper and then about the entire core there is a wrapping 14 to envelopthe entire core. This core and wrapping extend the complete length ofthe reel.

Caps designated generally 15 are provided at each end of the body andembrace the ends to stiften the same. Each of the end caps 15 is formedfrom a blank designated generally 16 (see FIG. 4) which is cut out fromsheet stock in the shape shown. This blank is printed and Scored forfolding, there being score lines 17, 17 to provide between them an endwall 18 and side walls 19, 19 extending from opposite sides of the endwall 18. Also there are scorings at 20, 20 at the ends of the end wallso that there are edge walls 21, 21 extending therefrom. Scorings alsoare provided at the edges of the side walls 19, 19 as at 22, 22, 22', 22to provide flanges 23, 23', 23, 23', at opposite ends of both side wall19. There is also a further scoring as at 24, 24 at the ends of flanges23', 23 for folding to provide flaps or tabs 25 extending beyond two ofthe flanges 23 for overlapping the side walls on the opposite side ofthe cap to be glued thereto.

After the blank 16 is cut, printed and scored, it is folded somewhatinto the form shown in FIG. 3 so that the side walls 19, 19 extend atright angles to the end wall 18 in a generally U-shape cross section.The edge walls 21 are folded at right angles to the end wall 18 toextend along the side walls 19. Then the ange 23 is folded in over theedge wall 21 at each end and then the ange 23' with the tab 25 attachedis folded in over the ange 23, thus making three plies of stock at thislocation. These plies of stock are glued together. This is all done asthe cap is being placed on the end of the body 10 and at the same timethe assembler bends the aps 25 over the opposite side wall 19 and gluewhich has previously been applied along the facing surfaces of the flapand the body secures the flap to the side wall and the cap in snugrelation on the body. This assembly being done about the end of thebody, a good tight fit is provided of this cap about the body.

The greatest pressure tending to collapse a reel of this sort has beenfound to exist across the edges of the cap at its junction with the endor the corner, and it is at this point that I have provided the threeplies of stock which gives an unusual stiffness at this location andthus one which provides for greater strength at the corner wherecollapsing is most apt to occur.
